A solid, square of floating ice measuring 5 m on a side and 0.41 meter thick floats partially submerged in water.

Determine the number of penguins that can stand on the ice block without any of them getting their flippers wet? (i.e. such that the top surface of the ice block floats at water level)? Assume that the mass of each penguin is 10 kg. Round your answer to the nearest whole number of penguins.

Assume the density of saltwater is 1030 kg/m³and the density of ice is 980kg/m³
